The French international's current deal expires at the end of the season, and the latest reports from the peninsula suggest that he has opted for a move to the San Siro, signing a four-year contract despite interest from other clubs such as Arsenal and Liverpool.
It's the kind of signing that will keep the Rossoneri in title contention, and with veteran Alessandro Nesta turning 35 this year and reportedly considering retirement, Mexes is a perfect fit to slot in alongside Thiago Silva in the centre of defence, particularly given he has no transfer fee attached to him.
Milan have excelled in quick and decisive action in the transfer market over the past 12 months, strengthening and rejuvenating a squad that was ageing and lacking in quality, having been left behind in the title challenge for several campaigns on the trot.
Massimiliano Allegri's side still aren't perfect, but they are title contenders, currently holding a five-point lead over city rivals Inter in the Scudetto race as a result of their incredibly effective activity off the pitch.
Juventus should take note, as these are the types of transactions they will need to make in order to build a side worthy of their history, rather than the disappointment that has plagued them over the last two seasons.
For example, Mexes may not have signed for the Turin giants because of the rivalry between Juventus and Roma, but Milan had already beaten the Bianconeri to one of their targets in Antonio Cassano and that represents yet another example of the failed transfer market swoops that have left Juventus lagging behind.

Mark van Bommel, a superbly experienced role player and midfield enforcer, was another who is now wearing the red and black for minimal expense, even if only in the short-term, but he provides certain guarantees in the centre of the pitch that will aid their season's late push. Kevin Prince Boateng, Robinho, Zlatan Ibrahimovic are all summer acquisitions that are performing well, and have reinforced the club.
A comparison of all the deals that Galliani and Juventus sporting director Giuseppe Marotta have signed off since the summer shows, shockingly, that if the teams were to take up all their current purchase options, the Bianconeri will have spent over €40 million more than their San Siro rivals this season.
But spending does not necessarily translate to success, nor do expensive players necessarily provide any guarantees on the pitch. Jorge Martinez, Simone Pepe, and Marco Motta have all essentially been big-money flops so far while Leonardo Bonucci, although he has plenty of promise, has yet to settle into the back line and justify his excessive €15.5m fee. Milos Krasic meanwhile has struggled to maintain his form from earlier in the campaign.
Turn your attention to the Milan's additions in the table above, and it is hard to argue that any of the purcahses have not been worth the transfer fee Milan paid for them - perhaps only Sokratis Papastathopoulos has not prodivded 'bang for his buck.'
Should Mexes arrive, he represents another signing that will cost so little, yet offer so much for Milan - a skill Juventus will need to hone when searching for talent, or yet another of their rebuilding seasons since Calciopoli will consequently be a disaster.
